1929. Divided and this application filed Gctober 1, 1929.

This invention relates to structures for 10- comotives and moreparticularly to a novel combination of side frame members, truck centerplate and pin, bumper bracket, brake cylinder brackets, crosshead guidebrackets, working cylinders, distribution valve chests and/or cylindersaddles, and is a division of my copending application Serial No.265,888, filed March 28, 1928,11ow Patent No. 1,731,511, of October 15,1929. An object of the invention is to provide a structure of such type,which will be strong, rigid, and simple; which will effect a substantialeconomy in the cost of manufacture; which will effect a substantialreduction in the number of separately form-ed connected members; andwhich will insure accurate alignment of the side frame members, bypermitting the necessary boring and slotting thereof to be performed inpairs.

Another object of the invention is to pro vide a crosstie member adaptedto rigidly couple together a pair of side frame mem bers, which crosstiemember may be employed to support a cylinder saddle and may haveincorporated with it a center pin, or a bumper bracket.

Other objects of the invention will hereinafter readily appear.

The improvement claimed is hereinafter fully set forth.

In the accompanying drawings: Figure 1 is an isometric view of afabricated structure embodying the invention the right hand side framemember being shown removed; Fig. 2. an isometric view of the removedside frame member; Fig. 3, a vertical transverse section taken on theline llllll of Fig. 1; Fig. 4:, a vertical longitudinal section taken onthe line lVlV of Fig. 1; Fig. 5, a vertical, transverse section taken onthe line VV of Fig. l; and Fig. 6, a plan view, the lower half being insection.

In the practice of the invention, referring descriptively to thespecific embodiment thereof which has been selected for exemplificatienherein, the frame comprises two counterpart side frame members, 10, eachcomprising a main side frame member 11, and front side frame member 12.Pref- Serial No. 396,425.

erably the main and the front side frame members are formed together asan integral casting, but itis within the contemplation of the inventionto form them separately. They are also preferably, but not necessarilymade of hollow or box cross-section.

Each front side frame member comprises inner and outer vertical sidewalls 12a and 12?); top and bottom horizontal walls. and 12d, connectinthe side walls; transverse walls, connecting the side walls andproviding sockets, or mortises 12h and 122', for the reception of crosstie tenons; and a vertical longitudinal flange 12 extending above thetop wall 120, and constituting a bracket for the attachment of a brakecylinder. The side walls 12a and 125 are provided with openings inregister with the sockets 12h and 122', and the top wall 120 is providedwith a transverse depression or pocket 12% adapted to receive a cylindersaddle. Suitable bolt holes 1% are provided in the side walls 12a and12?) for the reception of bolts for fastening the cylinder to the framemember.

A cross-head guide bracket 11a, is preferably, though not necessarily,formed integrally with, and projects laterally from, each main sideframe member 10.

The front side frame members 12. are rigidly secured together by a truckcenter plate cross tie member 13. and a bumper beam bracket cross tiemember 14. A The truck center plate and pin member 13. 1s disposedbetween and at the saddle pocket portion of the front side framemembers. is preferably, though not necessarily. formed as an integralcasting, and compi'ises horizontal top and bottom walls 13a and 137): acentral vertical tubular wall 130, connect ing the top and bottom wallsand projecting below the bottom wall to form a center-pin 13d; verticaltransverse end walls 136. obnnecting the top and bottom walls verticallongitudinal side walls 13;", connecting the top, bottom, and end walls;vertical longitudinal bracing walls 139, connecting the top. bottom, andtubular walls; vertical trans verse bracing walls 13h, connecting thetop,

bottom, tubular walls and side walls; and

tubular tenons or dowels 135, one projecting laterally from, andintermediate the length of, each side wall, the tenons being adapted tobe force or press fitted into the sockets 12h, of the front side framemembers, and welded to the walls thereof. The side walls 13;". areprovided with boltholes 13;; in line with holes 121, for bolting thecasting to the front side frame members, and the top wall 18% isprovided with openings 13X: to permit access to certain of the bolts.

The bumper beam lr; cltet cross tie member 1+. is disposed between andat the forward end of the front side frame members; preferably thoughnot necessarily. formed as an integral casting; and comprises, verticallongitudinal side walls 14a. vertical front and rear walls l i-Z) and llo. connecting the side walls, a horizontal wall lei-(Z, connecting theside, front, and rear walls, and tuljiular tenons or dowels 140, oneproject ing laterally from, and intermediate the length of. each sidewall. each tenon being adapted to be force or p 'ess fitted into one ofthe sockets 125, of the front side frame members and welded to the wallsthereof. The front wall 14]) is adapted to serve as a bracket for theattachment of a bumper beam. It is within the contemplation of theinvention to form the bumper beam integrally with the bumper cross tiemember.

Supported in the pockets 12b of the front side frame members, are twocounterpart integral castings 16, each comprisii'ifr a half saddle 16, acylinder 16?), and a distriliiution alvo chest 160. It is within thecontemplation of the invention to form the saddle. the cylinders. andthe distribution valve chests separately. or to combine them together,or with the front side frame members in any of the ways heretoforeknown.

\Vhile the l. nnper beam cross tie and the center pin cross tie havebeen shown as separately formed it is within the contemplation of theinvention to combine them in an integral casting.

While one of the preferred forms of construction has been shown. it isobvious that many variations in procedure. form. a rran gement. andconstruction of the parts can he made, and the invention is nottherefore limited to the particular embodiment disclosed, but includessuch. changes and modifications as come within the spirit and scope ofthe invention as set forth in the appended claims.
